Question

我有以下代码：

#!/usr/bin/python

import pandas as pd

df = pd.read_excel(io='http://www.iea.org/gtf/download/Export_GTF_IEA.xls', sheetname='Data', skip_footer=5, )

df = df.drop('Unnamed: 2', axis=1)
df = df.drop('Exit', axis=1)
df = df.drop('Entry', axis=1)
df = df.drop('MAXFLOW (Mm3/h)', axis=1)

df = df.T

df.to_csv('foo.csv', encoding='utf-8', sep='\t', header=False)

＃

输出样本如下所示：

print df
                              0        1           2           3        4    \

如何将时间戳转换为月末日期？

Answer 1

未正确设置标头，以便设置可以使用的正确标头

df.columns = df.iloc[0]
df.drop(df.index[:1], inplace=True)

Den将时间戳更改为您可以使用的月结束日期

df.index = df.index + pd.offsets.MonthEnd(0)

输出：

2008-10-31             0        0          0          0   152.81       0
